DETAILED DESCRIPTION

In general, according to one embodiment, a display device comprises a display, a circuit substrate, a plurality of connector terminals, a first cover, a second cover, and a fastening member. The display comprises a first face and a second face. The first face comprises a display screen. The second face is on an opposite side of the first face. The circuit substrate comprises a first side and a second side adjacent to the first side, and overlaps the second face of the display. The plurality of connector terminals are disposed at a vicinity of each of the first side and the second side of the circuit substrate. The first cover comprises a first opening exposing the connector terminals therethrough, and covers the second face. The second cover comprises a linking portion and a noncircular through hole, and covers the first opening across the first side and the second side of the circuit substrate. The linking portion is positioned in between the first side and the second side. The fastening member is inserted through the through hole of the second cover so as to fix the second cover, the circuit substrate, and the display.

An embodiment is described in detail below with reference to the accompanying drawings. For the sake of convenience in the following explanation, the directions are defined in the following manner. When viewed from the front of a display device 1, the leftward direction (or when viewed from behind, the rightward direction) is defined as the X direction, the upward direction is defined as the Y direction, and the depth direction (backward direction) is defined as the Z direction. In the accompanying drawings, arrows are illustrated to represent the abovementioned directions in the assembled state of the display device 1.

As illustrated in FIGS. 1 and 2, the display device 1 according to the present embodiment comprises a main body 3 and a leg 4 that supports the main body 3. The main body 3 comprises a built-in display 2 such as a liquid crystal display (LCD).

The main body 3 comprises a front face 3 a and a rear face 3 b on an opposite side of the front face 3 a. The main body 3 is configured to be thin in the front-back direction, is horizontally oblong in appearance when viewed from the front, and is formed in the shape of a flat rectangular parallelepiped. A front mask 5 a that covers a front face 2 a of the display 2 and that constitutes a housing 5 also comprises a rectangular opening 5 b formed thereon. Through the opening 5 b, the front face 2 a comprising the display screen of the display 2 is exposed. In the present embodiment, the front face 2 a comprising the display screen corresponds to a first face. A portion on the front face 2 a exposed via the opening 5 b is the display screen.

A rear cover 5 c that covers a rear face 3 b of the main body 3 and that constitutes the housing 5 also has an L-shaped depression 3 c formed thereon from the left-side area in FIG. 2 to the lower-side area in FIG. 2. Moreover, as illustrated in FIG. 3, a bottom face 3 d of the depression 3 c and a top face 3 e, which serves as a general surface of the rear face 3 b, have a difference in their respective levels, and a plurality of slit-like openings 3 f are formed therebetween. The openings 3 f are formed to open in a direction along the bottom face 3 d (rear face 3 b) (in the present embodiment, formed to open either laterally or downwardly). Through the openings 3 f are exposed a plurality of connector terminals 6. As is clear from FIGS. 2 and 4, the rear cover 5 c covers a rear face 2 b of the display 2. In the present embodiment, the rear face 2 b of the display 2 corresponds to a second face and the rear cover 5 c corresponds to a first cover. The openings 3 f extend up to the bottom face 3 d. Thus, interference between the rear cover 5 c and the connector terminals 6 can be prevented when the rear cover 5 c is mounted over the rear face 2 b of the display 2.

As illustrated in FIG. 4, a circuit substrate 7 is fixed to a rear wall 2 c, which constitutes the rear face 2 b of the display 2, with screws 8 serving as fastening members. In the present embodiment, as illustrated in FIG. 6, the connector terminals 6 are disposed at a vicinity of and along a lower side 7 a and a left-hand side 7 b adjacent to the lower side 7 a of the circuit substrate 7 positioned in the leftmost portion in FIG. 4. The examples of the connector terminals 6 include card sockets, universal serial buses (USBs), local area network (LAN) cable sockets, RCA terminals, D-terminals, S-terminals, DV terminals, radio frequency (RF) terminals, SCART terminals, serial digital interface (SDI) terminals, and audio pin terminals. The connector terminals 6 are exposed to the outside of the housing 5 through the openings 3 f formed on the rear cover 5 c. Meanwhile, the circuit substrate 7 comprises wiring patterns (not illustrated) designed using conductors and electronic components (not illustrated) other than the connector terminals 6 mounted thereon.

Herein, the connector terminals 6 are disposed at the vicinity of the lower side 7 a and the left-hand side 7 b of the circuit substrate 7, as illustrated in FIG. 6. Hence, in a configuration in which the connector terminals 6 are merely exposed through the slit-like openings 3 f, the periphery of the circuit substrate 7 (in the present embodiment, the lower side 7 a and the left-hand side 7 b) is also exposed through the openings 3 f together with the connector terminals 6. That mars the aesthetic appearance of the display device 1. Thus, in the present embodiment, a side cover 9 is disposed along the lower side 7 a and the left-hand side 7 b of the circuit substrate 7 as illustrated in FIG. 5. Thus, as illustrated in FIG. 3, the lower side 7 a and the left-hand side 7 b of the circuit substrate 7 is covered by the side cover 9. Therefore, the lower side 7 a and the left-hand side 7 b are prevented from being exposed to the outside through the openings 3 f. Herein, the side cover 9 partially covers the openings 3 f, and partially covers the lower side 7 a and the left-hand side 7 b of the circuit substrate 7 in a lateral fashion. In the present embodiment, the side cover 9 corresponds to a second cover and corresponds to a cover member. Moreover, in the present embodiment, the lower side 7 a of the circuit substrate 7 corresponds to a first side and the left-hand side 7 b of the circuit substrate 7 corresponds to a second side.

As illustrated in FIGS. 5, 7, and 8, the side cover 9 comprises a first portion 11, a second portion 12, and a linking portion 10. The first portion 11 is arranged along the lower side 7 a of the circuit substrate 7. The second portion 12 is arranged along the left-hand side of the circuit substrate 7. The linking portion 10 links the first portion 11 and the second portion 12 with each other. Regarding the side cover 9 according to the present embodiment, since the first portion 11 and the second portion 12 are linked by the linking portion 10, a smaller number of components are required as compared to the case when a separate cover is mounted for each of the plurality of sides. That enables achieving reduction in the time and efforts during manufacturing.

The first portion 11 comprises a first facing portion 11 a, a first bottom wall 11 b, and a first top wall 11 c. The first facing portion 11 a opposes the lower side 7 a of the circuit substrate 7, extends along the lower side 7 a in a belt-like manner, and rises from the rear face 2 b of the display 2. The first bottom wall 11 b is connected to the first facing portion 11 a at a side of the rear face 2 b, and extends in a belt-like manner along the rear face 2 b. The first top wall 11 c is connected to the first facing portion 11 a at a side opposite to the side of the rear face 2 b, and extends in a belt-like manner parallel to the rear face 2 b. Thus, due to the first facing portion 11 a, the first bottom wall 11 b, and the first top wall 11 c that are mutually connected; the first portion 11 is formed to have an S-shaped cross-section.

The second portion 12 comprises a second facing portion 12 a, a second bottom wall 12 b, and a second top wall 12 c. The second facing portion 12 a opposes the left-hand side 7 b of the circuit substrate 7, extends along the left-hand side 7 b in a belt-like manner, and rises from the rear face 2 b of the display 2. The second bottom wall 12 b is connected to the second facing portion 12 a at a side of the rear face 2 b, and extends in a belt-like manner along the rear face 2 b. The second top wall 12 c is connected to the second facing portion 12 a at a side opposite to the rear face 2 b, and extends in a belt-like manner parallel to the rear face 2 b. Thus, due to the second facing portion 12 a, the second bottom wall 12 b, and the second top wall 12 c that are mutually connected, the second portion 12 is formed to have an S-shaped cross-section.

On the first facing portion 11 a and on the second facing portion 12 a that are formed as vertical walls, openings 13 are formed in such a way that the connector terminals 6 are exposed therethrough. Each of the openings 13 is provided to each of the connector terminals. Accordingly, the lower side 7 a and the left-hand side 7 b of the circuit substrate 7 are prevented from being exposed through the openings 13. In the present embodiment, the openings 13 correspond to second openings.

As illustrated in FIGS. 5, 8, and 10, the linking portion 10 links together the first portion 11 and the second portion 12 arranged along a direction so as to intersect each other (in the present embodiment, arranged along mutually perpendicular directions). As illustrated in FIG. 5, when fixed in accordance with the shape of the circuit substrate 7, the linking portion 10 is bent in an arc-like manner around the outside of a corner 7 c formed between the lower side 7 a and the left-hand side 7 b of the circuit substrate 7.

As illustrated in FIG. 9, in the present embodiment, the linking portion 10 is not bent before installed in the display device 1. Accordingly, the first portion 11, the linking portion 10, and the second portion 12 are arranged in a linearly extended manner (in a rod-like manner). Thus, when the side cover 9 is transported from the manufacturing site thereof to the assembling site of the display device 1, the side cover 9 can be in the linear form (elongated form), as illustrated in FIG. 9. As compared to the bent form illustrated in FIG. 8, the elongated form makes it easier to stack a plurality of the side covers 9 in a more compact manner. This, according to the present embodiment, by keeping the side covers 9 in the elongated form upon manufacturing, transportation thereof becomes more efficient.

The linking portion 10 is bent before assembling the side cover 9 in the display device 1. In the present embodiment, the linking portion 10 is thinner than the first portion 11 and the second portion 12. More particularly, a width Wb (in the S direction) of the linking portion 10 is smaller than a width Wa (in the Z direction) of the first portion 11 and of the second portion 12. Besides, in contrast to the S-shaped cross-section of the first portion 11 and of the second portion 12, the linking portion 10 has a plate-like shape. Hence, the linking portion 10 has a lower resistance to bending than the first portion 11 and the second portion 12. Thus, by applying force to the first portion 11 and the second portion 12, the worker can bend the side cover 9 at the linking portion 10 and thus achieve the bent form of the side cover 9 in a relatively easy manner. For that reason, the linking portion 10 can be called a bending portion or an easily-deformable portion. Herein, in order to bend the linking portion 10 in a predetermined shape, the worker can press the linking portion 10 against a curved surface for pressing of a predetermined jig. Meanwhile, on the linking portion 10, at least a single folding line can be provided as a groove along the Z direction.

As illustrated in FIGS. 10 and 11, as compared to a top side 11 d of the first facing portion 11 a and a top side 12 d of the second facing portion 12 a positioned away from the rear face 2 b of the display 2, the linking portion 10 is positioned closer to the rear face 2 b. That makes it easier to prevent interference between a tilted portion 5 d of the rear cover 5 c and the linking portion 10. Thus, by avoiding interference with the linking portion 10, the tilted portion 5 d (see FIG. 3) formed on the rear cover 5 c enables achieving enhancement in the aesthetic appearance of the display device 1.

As illustrated in FIG. 8 and in FIGS. 12 to 14, the side cover 9 comprises a plurality of fixing pieces 14 each having a through hole 14 a formed thereon. In the present embodiment, the fixing pieces 14 are disposed at three locations in all, namely, a location at an end of the first portion 11 away from the linking portion 10 (first fixing piece 14A), a location at a middle part of the second portion 12 (second fixing piece 14B), and a location at an end of the second portion 12 away from the linking portion 10 (third fixing piece 14C). In the present embodiment, as illustrated in FIG. 15, each screw 8 inserted into the through hole 14 a of one of the fixing pieces 14 and into a through hole 7 e formed on the circuit substrate 7, and is screwed into a screw hole 2 e formed on a boss portion 2 d disposed on the rear wall 2 c of the display 2. As a result, the side cover 9 and the circuit substrate 7 is fixed to the display 2. Thus, in order to fix the side cover 9, the fixing configuration for the circuit substrate 7 (i.e., the fixing configuration comprising the screws 8 and the boss portions 2 d) is used.

As illustrated in FIG. 15, each fixing piece 14 protrudes toward the circuit substrate 7 from the first facing portion 11 a or the second facing portion 12 a opposing an edge of the circuit substrate 7 (in the present embodiment, the lower side 7 a or the left-hand side 7 b), and is mounted on a top face 7 d of the circuit substrate 7. Herein, although FIG. 15 illustrates the configuration of the second fixing piece 14B, the first fixing piece 14A and the third fixing piece 14C also have the same configuration.

Each fixing piece 14 is configured by cutting and raising the first facing portion 11 a or the second facing portion 12 a toward the circuit substrate 7. As a result, in an area on the first facing portion 11 a or the second facing portion 12 a which is closer to the rear face 2 b than the fixing piece 14, a void portion 15 is formed adjacent to the boss portion 2 d comprising the through hole 14 a through which the screw 8 is inserted. Because of the void portion 15, the boss portion 2 d is prevented from interfering with the first facing portion 11 a or the second facing portion 12 a. Moreover in such a configuration, since each fixing piece 14 is cut and raised from below to upward with respect to the top face 7 d of the circuit substrate 7, the suppress strength due to the springback phenomenon acts on that fixing piece 14 in the direction in which the fixing piece 14 is pressed toward the top face 7 d of the circuit substrate 7. Hence, such a configuration also makes it easier to maintain the relative positional relation between the circuit substrate 7 and the side cover 9. Meanwhile, each void portion 15 is covered by a side wall 5 e of the rear cover 5 c and is therefore not exposed.

At the leading end of each fixing piece 14, a warp portion 14 b is formed with the tip thereof bent in a direction away from the top face 7 d of the circuit substrate 7. When the side cover 2 is disposed along a periphery of the circuit substrate 7 (along the lower side 7 a or the left-hand side 7 b), the side cover 9 is brought close to the circuit substrate 7 in a lateral direction. Thus, because the warp portion 14 b is formed at the leading end of each fixing piece 14, the fixing piece 14 can be prevented from being interfered by the circuit substrate 7. Therefore, it becomes possible to reduce difficulty in arranging the fixing piece 14 at the predetermined position.

The through hole 14 a formed on each fixing piece 14 is larger in size than the outside diameter of the screws 8. Besides, in the present embodiment, as illustrated in FIGS. 16 and 17, some of the through holes 14 a comprise one or more locking side portions 14 c formed therein to restrict the side cover 9 from being out of position. The locking side portions 14 c are formed as rectilinear edges so as to restrict the movement of the side cover 9 in the direction perpendicular to the locking side portions 14 c. Thus, in the present embodiment, the through holes 14 a are formed in noncircular by the locking side portions 14 c, which increases accuracy in the positioning the side cover 9. As illustrated in FIG. 16, the through hole 14 a formed on the first fixing piece 14A has a locking side portion 14 c 1 that restricts the downward movement of the side cover 9 when viewed from behind and has a locking side portion 14 c 2 that restricts the leftward movement of the side cover 9 when viewed from behind. Moreover, as illustrated in FIG. 17, the through hole 14 a formed on the second fixing piece 14B has the locking side portion 14 c 2 that restricts the leftward movement of the side cover 9. Meanwhile, in the second fixing piece 14B, the side cover 9 is allowed to have positional degree of freedom in the direction along the left-hand side 7 b of the circuit substrate 7. That eliminates the difficulty that may otherwise arise while fixing the corresponding screw 8.

Each of the locking side portions 14 c restricts the lateral movement (in the present embodiment, downward movement or leftward movement when viewed from behind) of the side cover 9. For that reason, it becomes possible to prevent the side cover 9 from interfering with the tilted portion 5 d or the side wall 5 e (see FIG. 3) of the rear cover 5 c.

As illustrated in FIG. 8, on the first top wall 11 c and the second top wall 12 c are respectively formed through holes 11 e and 12 e with the aim of avoiding interference with the screws 8, or tools, or the connector terminals 6. However, at the leading end side with respect to the portions having the through holes 11 e and 12 e formed thereon (i.e., on the distant side from the first facing portion 11 a and the second facing portion 12 a), no notches are formed but bridge members 11 f and 12 f are disposed that extend in the longitudinal direction. That enables preventing a decline in the tolerance at the portions having the through holes 11 e and 12 e formed thereon. Besides, when external force is applied to the side cover 9 for the purpose of bending it at the linking portion 10, it becomes possible to bend the linking portion 10 in a more reliable manner.

Meanwhile, as illustrated in FIG. 18, regarding the relatively larger openings 13 reaching the top side 11 d of the first facing portion 11 a or the top side 12 d of the second facing portion 12 a (i.e., the openings 13 reaching boundary region of the first top wall 11 c or the second top wall 12 c), the openings 13 are notched up to the first top wall 11 c or the second top wall 12 c so as to prevent deformation such as warping from occurring at the borders of the openings 13.

Moreover, as illustrated in FIG. 19, regarding the openings 13 formed opposite to those connector terminals 6 in which inserts such as cards or the like are inserted, a bending portion 13 a is formed in an inwardly-bending manner at the border of each opening 13. Because of that, when inserts are inserted in the openings 13, it becomes possible to prevent interference between the inserts and the borders of the respective openings 13 and thus prevent the inserts from getting damaged.

In the abovementioned configuration, the circuit substrate 7 and the side cover 9 are fixed to the rear wall 2 c of the display 2 in the sequence illustrated in FIGS. 20A to 20C. Firstly, as illustrated in FIG. 20A, the worker places the circuit substrate 7 at a predetermined position on the rear wall 2 c (S1). At S1, without fixing the side cover 9, the worker can only fix the circuit substrate 7 to the display 2 by tightening in advance only those screws 8 which are used to fix the circuit substrate 7.

Subsequently, as illustrated in FIG. 20B, the worker brings the first portion 11 of the side cover 9 closer to the lower side 7 a of the circuit substrate 7 from below, and places the first portion 11 at a predetermined position by abutting it against the lower side 7 a (S2). At S2, the linking portion 10 of the side cover 9, which is placed at the predetermined position, is already bent. That is, before performing S2, the side cover 9 is bent at a bending angle shallower than the bending angle in the assembled state thereof (S1 a). Here, the predetermined position is a position that allows the through holes 7 e of the circuit substrate 7 to overlap the respective through holes 14 a of the fixing pieces 14.

Then, as illustrated in FIG. 20C, the worker bends the side cover 9 to a greater extent so as to bring the second portion 12 closer to the left-hand side 7 b of the circuit substrate 7 from the left side, and places the second portion 12 at a predetermined position by abutting it against the left-hand side 7 b (S3). Here, the predetermined position is a position that allows the through holes 7 e of the circuit substrate 7 to overlap the respective through holes 14 a of the fixing pieces 14. Since the side cover 9 is already bent by a smaller extent at S1 a described above, it becomes possible for the worker to further bend the side cover 9 without much difficulty at S3. Besides, it also becomes possible to achieve a highly accurate bent form of the side cover 9 (i.e., to ensure less variability in the bent form of the side covers 9).

Subsequently, the worker inserts the screws 8 into the respective pairs of the through holes 14 a and 7 e, and tightens the screws 8 in the screw holes 2 e of the respective boss portions 2 d disposed on the rear wall 2 c of the display 2 (S4). Here, the tightening of the screws 8 is performed in an order of the first fixing piece 14A, the second fixing piece 14B, and the third fixing piece 14C. The through hole 14 a formed on the first fixing piece 14A has two locking side portions 14 c, the through hole 14 a formed on the second fixing piece 14B has a single locking side portion 14 c, and the through hole 14 a formed on the third fixing piece 14C has no locking side portion 14 c. Such a configuration makes it possible to enhance the accuracy of positioning the side cover 9 as well as to eliminate the difficulty that may otherwise arise while fixing the screws 8. Subsequently, the rear cover 5 c is disposed to achieve the configuration illustrated in FIG. 2.

Embodiments are not limited to the aforementioned embodiment, and the embodiment described above can be modified in various ways. For example, although the abovementioned embodiment is explained with reference to a display device comprising connector terminals, the embodiment is also applicable to other electronic devices such as a personal computer comprising connector terminals. Moreover, although the abovementioned embodiment is explained with reference to the case of disposing connector terminals at the lower side and the left-hand side of the circuit substrate, the embodiment is also applicable for the case when connector terminals are disposed at other sides of the circuit substrate. Furthermore, the first facing portion and the second facing portion can be suitably interchanged. Moreover, for the purpose of fixing the components, fastening members other than screws, such as clips, can also be used. Moreover, the fastening members can be used to fix the second cover (cover member) not to the rear wall of the display but to another component such as the housing.

Besides, regarding the display, the circuit substrate, the connector terminal, the opening, the first cover, the rear cover, the linking portion, the through hole, the second cover, the cover member, the side cover, the fastening member, the second opening, the bending portion, the first facing portion, the second facing portion, the top side, the fixing piece, the warp portion, the locking side portion, the first side, and the second side, the specifications (method of operation, structure, shape, material, size, length, width, thickness, angle, number, arrangement, position, etc.) can be suitably modified.

According to the embodiments, it is possible to provide a display device that can be manufactured with less time and efforts.
